ABSTRACT
Internet of Thing (IoT) and robot technology is a very popular research topic. Especially in the application of Industry 4.0, it is the most basic and important part. However, related security and application system development often have many problems. For example, the integration of various communication interfaces and data formats, and the rapid establishment of application systems. Therefore, this paper uses MQTT protocol and AES encryption technology to develop a Web-based SCADA system. This Web-based SCADA uses drag-and-drop operation, and users can quickly build a WYSIWYG (What You See Is What You Get) application system. Moreover, with the characteristics of MQTT message transmission, users can choose to transmit the device's message as it is or to process the data before transmitting when creating the SCADA system. And these messages will be encrypted by AES, making the whole system safer and more efficient. Finally, by collecting different communication protocols and integrating multiple communication interfaces, this SCADA can be connected to many PLCs and other equipment, so that the industry can build application systems quickly and at low cost..
Keywords: Internet of things (IoT), Root, MQ telemetry transport (MQTT), AES, Supervisory control and data acquisition (SCADA)
